Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is used in coin exchange machines, various vending machines, game machines, etc., and coins and other articles stacked in a storage cylinder (in this specification, coins). Abbreviated as ") is dispensed from the lower end of the stack one by one or several coins.

(Prior Art) Conventionally, as this type of dispensing device, for example, Jikho 57-60125
As described in the publication, a coin storage cylinder for storing a large number of coins in a stack, a connecting pipe of the same inner size connected to the lower end of the coin storage pipe, and a tip portion within the cross-sectional circle of the connecting pipe. Is located in the connecting pipe and reciprocates between the projecting position in which is located and the retracted position located outside the cross-section circle, or the coins in the lowermost stage and the coins in the lowermost stage and a plurality of coins that are sequentially stacked above. , A coin pushing member adapted to push out coins to the outside of the connecting pipe at the same time to dispense the coins is known.

However, this type of dispensing device conventionally used is
As an actuator for operating the coin pushing member, for example, an electromagnet device and a spring are used as described in Japanese Utility Model Publication No. 57-60125 mentioned above, and the operation of the coin is caused by the rapid operation. Recently, it has become a problem as noise due to the problem of clogging and loud operation noise.

According to Japanese Patent Publication No. 53-28237, the rotary cam is engaged with the stroke edge of the feed plate having the step portion, while the rotary cam is released from the stroke edge of the feed plate at the coin biting position. The structure is shown for the purpose of preventing the burnout of the motor due to the coin pushing member being caught in the coin, as opposed to the clogging of the coin.

However, with this technology, even if it is possible to prevent motor burnout due to being bitten by a coin, if the coin becomes clogged, on the contrary, the rotating cam is released from the stroke edge of the feed plate. Is impossible, and on the contrary, there is a drawback that a motor burnout occurs.

(Problems to be Solved by the Invention) The present invention is to provide a coin payout device of the above-described type in which the above-mentioned coin clogging does not occur and there is no noise during operation.

(Means for Solving the Problem) Therefore, according to the present invention, the coin cylinder 1 including a plurality of vertically stacked coins is moved by the drive device 4 so that the coin cylinder 1 can move toward and away from the coin cylinder 1, In a coin payout device having a coin push-out member 3 that pushes out and pays out the coin from the lower side of the tubular body, a spring 9 for urging the coin push-out member to a projecting position in a direction of approaching the coin tubular body, A flat plate-shaped drive member 5 integrally connected to the coin pushing member, a circular hole 6 formed in the flat plate-shaped drive member in a circular shape, a circular plate 7 rotated by the drive device, and the circular plate. An eccentric pin 8 which is eccentrically arranged on a plate and which engages with the circular hole and draws out the coin pushing member to a retracted position in a direction away from the coin cylinder. Equipment can get. That is, an electric motor is used as an actuator, a flat plate-shaped driving member 5 is integrally coupled to the coin pushing member 3, a circular hole 6 is provided in the flat plate-shaped driving member, and an eccentric pin is provided on a disk 7 rotated by the electric motor 4. 8 is provided, and the eccentric pin is engaged with the inner peripheral surface of the circular hole of the drive member, and the coin pushing member is pulled out from the protruding position to the retracted position through the engagement of the eccentric pin and the circular hole by the rotation of the disc. The coin pushing member 3 was urged by the spring 9 so as to project to the projecting position.

(Operation) While the disc 7 is rotated once by the electric motor 4, after the coin pushing member 3 is pulled out from the protruding position to the retracted position through the circular hole 6 that engages with the eccentric pin 8 on the disc 7, Along with the rotation of the disc 7, the spring 9 causes the coin pushing member 3 to again project to the projecting position to push out the coin.

When the coin pushing member 3 is pushed forward to the projecting position by the spring 9, even if the coin pushing member 3 is stuck in the connecting pipe 2 and the coin pushing member 3 does not move toward the projecting position, the eccentric pin 8 on the disc 7 is pushed. Can move in the circular hole 6 of the drive member 5 and rotate the disk 7 once, so that the electric motor 4 will not be overloaded due to a coin jam.

Furthermore, since the eccentric pin 8 is engaged with the driving member 5 by the circular hole 6 on the disc 7 rotated by the electric motor 4, the pushing operation of the coin pushing member 3 by the spring 9 is suppressed, and thus The spring 9 prevents the coin pushing member 3 from being suddenly pushed to the projecting position and pushes out the coin sharply. Therefore, the coin that is about to be pushed rapidly does not pass smoothly from the inside of the connecting pipe 2 into the payout pipe. Coins are not clogged by being caught between the connecting pipe and the payout pipe, and the coins are relatively quietly and smoothly paid out without hitting the pipe wall strongly.

(Embodiment) The drawing shows one embodiment of the present invention, in which 11 is a fixed mount having a rectangular planar shape, a coin payout pipe 12 is provided at one end of the fixed mount, and the coin payout pipe 12 communicates with the coin payout pipe 12. Thus, the connecting pipe 2 is provided, and the coin storing cylinder 1 having the same inner diameter is detachably connected to the connecting pipe 2 by the screw portion 13. The mounting plate 14 of the electric motor 4 is fixed to the other end of the fixed mounting base 11 with a screw 15, and the disc 7 is fixed with a screw to the output shaft 16 of the electric motor 4 which extends through the mounting plate 14 and extends downward. .

The coin push-out member 3 is fixed below the connecting pipe 2
A spring-loaded steel ball 18 is mounted on a sliding pedestal 17 provided on 11
The flat plate-shaped drive member 5 which is pressed by means of and is slidably supported by the coin push-out member 3 and is integrally formed with the coin push-out member 3 has the engaging screw 28 in the guide groove 27 of the slide guide plate 26 mounted on the fixed mount 11. An eccentric pin 8 is engaged with the circular hole 6 of the drive member 5 and is guided below the mounting plate 14 so as to move linearly in translation.

A buffer arm 19 is provided at an intermediate position between the coin pushing member 3 and the flat plate driving member 5 so as to project from both ends of the coin pushing member, and hooks 20 are formed at both ends of the buffer arm 19. Each one end is connected, and the other end of the spring 9 is connected to the fixed mount 11 at 30 to urge the coin pushing member 3 so as to always project to a position projecting into the cross section circle of the connecting pipe 2. There is.

Coin support bases 21 are provided on both sides of the portion of the coin push-out member 3 projecting in the cross-section circle of the connecting pipe 2, and the thickness of the support base 21 is set to a value corresponding to the thickness of the coin push-out member 3 of a required number of coins. It is formed as thin as the thickness.

Reference numeral 22 denotes a residual coin detecting switch, which has a through hole 23 in which the tip of the actuator 31 is formed on the peripheral wall of the connecting pipe 2.
After that, the connection tube 2 is projected to a position where it can come into contact with the coin so that a signal can be generated and indicated when the number of coins in the tube becomes empty or less than a predetermined number.

Reference numeral 24 denotes a payout counting switch, which is fixed on the connecting pipe 2 and is provided so as to be operated by a switch operating rod 25 standing upright on the buffer arm 19.

(Effect of the Invention) According to the present invention, it is possible to provide an extruding type coin dispensing device which operates smoothly and produces quiet operation noise.
